Answer:
Soils are the key ingredient for the plants and crops to grow. A large amount of soil is eroded every year due to the practice of farming. This is about 25 billion tons of soils.
Due to the various type of agricultural practices, the topsoil comprising the valuable minerals are continuously eroded by factors such as wind and water. This results in the increasing loss of soil fertility, and also it can lead to the occurrence of droughts, sandstorms, and dust bowls.
Dust bowls are the region where there occurs no rainfall and absence of vegetation, and soils are eroded drastically making a sandy dust environment, and affecting the ecosystem.
In order to prevent these effects, certain steps must be taken, and they are as follows-
- Planting more trees and crops so that the wind cannot cause much impact on the area.
- The waste vegetative particles and matters must be allowed to distribute evenly over the surface of these areas, so that wind cannot easily transport these sediments.
- Mulching of the soil must be done.
- By constructing the retaining walls.
<u>Answer:</u>
<em>Convergent plate boundary is rich in gold and silver.
</em>
<em></em>
<u>Explanation:</u>
There are three types of plate boundary such as Convergence, Divergence and Transform plate boundary. Most metallic minerals found in convergence plate boundary. Gold and silver are deposited in both convergent and divergent margins but rich in Convergent plate margin. Precious metals such as plutonium, gold, silver, etc. are mostly found in convergence of two plates. Convergence occurred in three ways such as Continent–Continent, Ocean–Ocean, Continent–Ocean.
Answer:
Well.....
Explanation:
There is a possible chance that humans would survive with out plans but they could also not survive without plans. I chose to be on the side where humans wouldn't survive without plans. The reason that they would not be able to survive would be because if they had no plans and most people rely on the plans for surviving that why I think they wouldn't survive.
But on the other hand, if they knew surviving skills or at least had a back up plan if they lost their plans, they would definitely survive. I hope this is the answer your looking for, This knowledge came from my head.
Answer:
7. This is an earthquake fault.(I'm sorry idk what your teacher calls it)
8. Earthquakes are due to plate tectonics, because when they move it causes trouble.(not very scientific definition sorry)
9. You can tell this is a fault because a fault is where plate tectonics slip. It causes a sort of fracture. (Also I recognize this photo it's from New Zealand an earthquake happened there in 2016)
Hope this helps
